This isn't exactly a horror novel, but it was horrifying. It scared the pants off me. I don't want to say too much about it to avoid spoiling any potential surprises. Carlson tells the story of a nanotech plague, and its few survivors, in a spare, fast style. There are plot twists aplenty, and neither the heroes nor villains are as simple as they might first appear. Strongly recommended if you like science fiction, apocalyptic fiction, or well-written and scary fiction.
